✦ Synopsis

Results on a vertical cavity surface emitting laser with InGaAs/GaAs quantum wells and a hybrid AIAs/GaAs Bragg reflector with a metal top mirror are presented. The structure has a threshold current density of 2.1kAcm -2 and a 6% external quantum efficiency (uncorrected for substrate absorption and internal reflection losses).

A laser operating at low threshold current is indispensable for the construction of superparallel optical interconnections. Initially we examine the current threshold characteristics of surface emitting InGaAs/GaAs lasers, and demonstrate the possibility for working with a threshold current below 10

The vertical-cavity surface-emitting laser (VCSEL) operating with low threshold current is a promising way to realize future parallel optical interconnects. In this study, we propose a novel structure of p-type delta-doped In-GaAs/GaAs quantum wells for low-threshold, high-speed VCSELs. Edge-emittin

## Abstract Tunable vertical cavity surface‐emitting lasers (VCSELs) are potentially useful for future optical networks. To date, the most successful mechanics to realize wavelength tunability in tunable VCSELs resides in MEM‐VCSELs via microelectromechanical (MEM) technology. The key parts to acco

We report on a new structure design and optical properties of the coupled edge and horizontal cavity vertical emitting laser (CE-HCSEL) with emission wavelength of ∼1160 nm based on InGaAs/GaAs double quantum well structure in the active layer. The CE-HCSEL incorporates two oxide stripe lasers coupl
